John R. Helliwell is emeritus professor of chemistry at the University of Manchester, United Kingdom. He has a DPhil in molecular biophysics from the University of Oxford and a Doctor of Science Physics degree from the University of York. He has presented crystallography and research to diverse audiences in academic and scientific civil service contexts and has served the International Union of Crystallography as a representative in several global organisations. He has also chaired science advisory committees in Japan, Australia, the United States and Europe. He received the Patterson Award of the American Crystallographic Association and the Perutz Prize of the European Crystallographic Association, and is a fellow of the Institute of Physics, the Royal Society of Chemistry, the Royal Society of Biology and the American Crystallographic Association.
